First release 2007 on the audio CD sampler "Various Artists - In A Spin" by Kara Moon Collective. Second release 2012 in digital format on "Beatslaughter - Serenity EP" by Phonocake. Third release 2015 is in Renoise native format. :)
I've tried to get as close to the original version as possible and while it's not 100% accurate i'm quite happy with the result. You can download my EP containing this song at:
